Spontaneous resolution of popliteal artery thrombosis.

Spontaneous resolution of thrombosis of the systemic arteries is a rarely documented phenomenon. Two patients are described in whom thrombus within the popliteal artery was noted to lyse spontaneously. This resulted in a decrease in ischemic symptoms and was documented by angiography. The spontaneous improvement that occurs in some patients with atherosclerotic femoropopliteal disease may be due to this mechanism as well as to increased flow via collateral vessels.

Results of perioperative measurements of ankle-brachial index in popliteal artery entrapment syndrome.

OBJECTIVE: The purpose of this study was to demonstrate whether there is postoperative improvement in blood flow in the affected limb after surgical decompression in popliteal artery entrapment syndrome (PAES). For this purpose, the simple method of measuring Doppler ankle pressure with and without provocation was used preoperatively and postoperatively. PATIENTS AND METHODS: Doppler ankle pressure was measured preoperatively and postoperatively in neutral position (n=32) and with provocation (forced plantar flexion of the foot; n=32) in 32 limbs in 23 patients with PAES (19 men, 4 women; average age, 38.24 +/- 12.25 years) operated on between January 1, 1986, and December 31, 2000. The reference method was angiography with provocation in 18 patients and duplex ultrasound scanning in 14 patients. RESULTS: Patients were assigned to one of two groups (A and B) on the basis of ankle-brachial index (ABI) at rest. Group A (mean age, 38.19 +/- 11.60 years) included all limbs (n=24) with ABI>0.9 preoperatively, and group B (mean age, 42.39 +/- 14.38 years) comprised all limbs (n=8) with ABI<0.9. Improvement in ABI under provocation after operation (group A, P<.0001; group B, P<.0004) was highly significant. In group B there was also a highly significant difference in ABI in the neutral position before and after operation (P=.0044); this could not be demonstrated in group A. Angiography or duplex sonography postoperatively did not provide any additional information. CONCLUSION: Our results indicate that determination of ABI alone, with and without provocation, is sufficient as a postoperative follow-up examination to appraise decompression and for quality assurance of PAES. Compared with other more elaborate instrumental methods, measurement of ABI is relatively noninvasive, quick and easy to carry out, effective, and inexpensive.

Percutaneous transluminal angioplasty of the ilio-femoro-popliteal arteries: initial and long-term results.

Percutaneous transluminal angioplasty has been widely used for dilatation and recanalization of occluded or stenosed vessels, but clinical experience in Japan is not extensive. Follow-ups of 78 ilio-femoro-popliteal angioplasties were performed for up to 51 months to assess the initial and long-term results. The initial technical success rate was 91%. The three-year cumulative patency rate was 75%. This study demonstrates that the long-term results of PTA of ilio-femoro-popliteal arterial lesions are competitive with reconstructive surgery. PTA should be the treatment of choice in patients with atherosclerotic narrowing or occlusion of the lower extremities.

[Percutaneous aspiration embolectomy of the popliteal artery].

Twenty-eight patients (17 women, 11 men, average age 67 years, range 40-85 years) with embolic occlusions of the popliteal arteries were treated by aspiration embolectomy. 6 patients were in clinical stage IIb and 22 in stage III. In 25 of the 28 patients the occlusion was treated successfully. Complications could be treated non-surgically at the same time. 2 of the patients died within the first week of cerebral emboli, 2 further patients suffered recurrent emboli in the treated extremity during the first month. 17 patients who were followed up for six months were free of recurrences.

Treatment of recurrent femoral or popliteal artery stenosis after percutaneous transluminal angioplasty.

PURPOSE: This study was undertaken to compare repeat percutaneous transluminal angioplasty (rPTA), arterial reconstruction, and noninvasive therapy for treatment of patients with recurrent stenosis after PTA of the superficial femoral or popliteal artery. METHODS: From 1983 to 1993, 93 patients were treated for recurrent femoropopliteal stenosis. Indication for treatment was claudication in 72 patients, rest pain in 9, and ischemic ulcer in 12. Thirty-six patients (38%) were treated with arterial bypass, 35 (38%) with rPTA, and 22 (24%) with exercise and medication. Patients were monitored with clinical examination, ankle-brachial indexes, and duplex scanning. Follow-up ranged from 6 to 110 months (mean 42 months). RESULTS: With life-table analysis, the clinical and hemodynamic success of patients treated with rPTA was 41% at 1 year, 20% at 2 years, and 11% at 3 years. For patients treated with arterial bypass, the primary graft patency rate was 84%, 72%, and 72% at 1, 2, and 3 years, respectively. The secondary graft patency rate was 94%, 88%, and 88% at the same intervals. All patients with patent grafts were symptom free. All 22 patients treated with noninvasive therapy continued to have symptoms, but none required amputation during follow-up (range 6 to 108 months). Overall, patients with claudication did better than those treated for rest pain or an ischemic lesion after either rPTA or arterial bypass, but no other variable was statistically significant in predicting outcome. CONCLUSIONS: This study finds that arterial bypass is safe and more effective than rPTA in treating patients with recurrent stenosis. Preoperative evaluation is unable to select patients likely to benefit from rPTA. Repeat PTA should be reserved for patients with limited life expectancy or contraindications to operation.

Popliteal arterial injuries associated with fractures or dislocations about the knee as a result of blunt trauma.

A total of 73 patients with popliteal arterial injuries due to blunt trauma were treated at the Los Angeles County/University of Southern California Medical Center between January 1975 and January 1986. The injuries resulted from high-energy trauma (70% were motor-vehicle-related), and were associated with a variety of fractures and dislocations about the knee. Forty-eight of the patients (66%) had open injuries, 27% of which became infected; the infection rate for all injuries was 22%. The average time from injury to anastomosis was 14.6 hours. The overall amputation rate in the series was 15%. Ten of the 11 amputations were associated with open, type III fractures. The amputation rate did not correlate with type of fracture, delay in diagnosis, or delay in surgery of up to 24 hours, but was directly related to the degree of soft-tissue trauma.

[Dislocation and fractures around the knee with popliteal artery injury: A retrospective analysis of 54 cases].

A retrospective multicentric series of 54 cases of knee trauma with acute ischemia by popliteal artery injury were analyzed. These high-energy traumas involved 25 dislocations and 29 fractures, 11 involving distal femur, 15 the proximal tibia and 3 a floating knee. There were 45 men and 7 women, mean age 42 years. Thirty-three patients suffered multiple injuries. The knee injury was open in 25 cases and associated with sciatic paralysis in 32. Vascular repair was almost always achieved with bypass surgery. An external fixator was used in 39 patients. Vascular repair was unsuccessful in three cases requiring amputation, all three cases involving fractures. There were also six secondary amputations due to muscle necrosis or septic nonunion. The rate of complete recovery of the sciatic was 25%. The rate of nonunion was 37%, half due to infection. Outcome assessed at at least one year follow-up was moderate with frequent functional sequelae. The analysis of these results and data reported in the literature provided indications for diagnostic and therapeutic propositions.
